Responsible person for each step of IDoc configuration

Hi Friends,

My company is new to IDocs and I have to configure the 1st IDoc here. I am aware of the ABAP part of creating segment and basic type creation and also writing the function module.

Can you tell me the responsible team like the basis & functional team for the other activities like the maintain partner profiles, maintain logical system, RFC destination, distribution model, port , etc., Since there is no functional person in my team I'll have to justify if I need someone's assistance.

Can I single handedly do it with research or would I need functional help ? Please advice.
